Evolutionary models from BEX-Hot-COND03. The model curves are a function of R and log(g), which are represented in terms of their age and T_eff variations by two different color scales. The red-yellow lines represent iso-mass curves; the gray lines show iso-temperature curves; and the blue-white scale gives the age variations. For AF Lep b the predicted values of T_eff range from 950 to 1200 K and of R between 1.2 and 1.4 R_Jup; log(g) ~ 3.8 dex using the absolute magnitudes from the photometry points published by De Rosa et al. (2023; black) and Mesa et al. (2023; blue). The errors from the magnitude values were propagated onto log(g) and R.
